Sennheiser RS 170 full review
You won’t be carrying Sennheiser’s RS 170 headphones around with you when you’re travelling, but they’re an excellent choice when you want to sit at home and wallow in your favourite tunes.
Like AKG, Sennheiser has opted for the Kleer technology to provide lossless CD-quality streaming audio. But while the Kleer transmitter provided with the AKG headphones is small enough to slip into your pocket and carry around with you, Sennheiser’s transmitter is the size of a wireless router and requires a mains power supply.
A non-portable design like that might seem rather pointless for use with an iOS mobile music player. However, there are many who have got rid of their old hi-fi systems and CD players, and now use their iPhone, iPod or iPad as their home music system.
There’s no doubt that the RS 170s are great for use at home. The audio quality is excellent, with a rich, warm tone and firm, punchy bass. It’s superior to any of the Bluetooth headphones in this group, and more than a match for the even more expensive AKG headphones too.
The RS 170s are perfect for using around the home
The large transmitter also has a better range than Bluetooth – up to 80m, compared to 10m for Bluetooth – and we were able to wander freely without the slightest pause in the music playback. The only minor disadvantage is that the headphones require two AAA batteries, rather than having their own internal battery. However, Sennheiser does include a pair of rechargeable batteries with the headphones.
